The matrix potential value can be checked

Second, product characteristics 　　The soil moisture characteristic curve is usually measured by pressure membrane (chamber) and centrifuge. The author was informed that recently,　6.　　The soil moisture characteristic curve can reflect the water holding and releasing characteristics of different soils, and it can also understand some soil moisture constants and characteristic indexes of a given soil. 5., Ltd. Therefore, the soil water characteristic curve is an important and basic tool for studying soil water movement, adjusting and using soil water, and performing soil improvement.

If the soil moisture content is measured, the matrix potential value can be checked according to the soil moisture and soil characteristic curve, so as to judge the effective degree of the soil moisture content for plants. After more than 40 years of development, has successively designed and produced centrifuge products in various fields.　　About Shanghai The H1400pF soil high-speed refrigerated centrifuge developed and produced this time is a centrifuge product specialized in determining soil pF curve. The centrifuge method is simpler and time-saving than other methods, can measure a wider range of suction, and is widely used in soil moisture dynamic simulation. water characteristic curve.

has developed a special centrifuge for measuring soil pF curve 400pF high-speed refrigerated centrifuge for soil. is a professional centrifuge company certified by the FDA in China. The matrix potential of soil water (or soil water suction) changes with the change of soil water content. It effectively ensures the accuracy of the collected water and enables the calculation of parameters And the basis is guaranteed.

The concept of Tube Assembly Machine moisture characteristic curve., Ltd. 4.[Pharmaceutical Network Enterprise News] The soil moisture characteristic curve can reflect the water retention and release characteristics of different soils, and it can also understand some soil moisture constants and characteristic indexes of a given soil..The centrifuge products produced are of reliable quality, stable performance, and complete specifications. For example, when the suction power approaches 0, the soil is close to saturation, and the moisture state is dominated by capillary gravity water; when the suction power increases slightly and the water content decreases sharply, use a negative pressure head
